The granite cliffs and boulders of Mount Buffalo appear multi colored and while this is true most of the colors are actually the mosses, lichens and other micro plants that cover the rock. Lichens (while not actually a plant) are found in an amazing range of colors from bright orange through to a range of greens, browns and greys.

Lichens are amazing and were among the first living things to colonize the land and are not actually a single plant but are a symbiotic relationship between a number of living things. A definition of a lichen is

A
lichen is a composite organism that arises
from algae or cyanobacteria (or both) living among filaments of a fungus
in a symbiotic relationship. The combined life form has properties that
are very different from the properties of its component organisms.
Lichens come in many colors, sizes, and forms.
